Answer: 99 in²
Explanation:
We can use the given formula for a triangular prism. We will substitute our known values and solve.
Surface Area = length * base perimeter + (2 × base area)
Surface Area = length * (1.5 in + 2 in + 2.5 in) + (2 ×
)
Surface Area = 16 * (6 in) + (2 ×
)
Surface Area = 16 in * (6 in) + (3 in²)
Surface Area = 96 in² + 3 in²
Surface Area = 99 in²
